simplify ln((-1)/(x^2)e^x)

Solution

simplify

ln (\frac{- 1}{x ^{2}} e^{x})

Solution

ln (- 1) - 2 ln (x) + x

Solution steps

ln (\frac{- 1}{x ^{2}} e^{x})

Apply log rule:

lo g_{c} (ab) = lo g_{c} (a) + lo g_{c} (b)

ln (\frac{- 1}{x ^{2}} e^{x}) = ln (\frac{- 1}{x ^{2}}) + ln (e^{x})

= ln (\frac{- 1}{x ^{2}}) + ln (e^{x})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (e^{x}) = x ln (e)

= ln (\frac{- 1}{x ^{2}}) + x ln (e)

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{- 1}{x ^{2}}) = ln (- 1) - ln (x^{2})

= ln (- 1) - ln (x^{2}) + ln (e) x

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (x^{2}) = 2 ln (x)

= ln (- 1) - 2 ln (x) + x ln (e)

x ln (e) = x

= ln (- 1) - 2 ln (x) + x
